This tile, I always used it as one of the most powerful of the game ; a mix between teleport and floating chamber. That is, you put it WHERE you want (adjacent, obviously) and then you put you hero on it.
But, some days ago, a friend made me realize something : do you actually have to put it nearby your hero so that is automaticly done move stays regular ? that is, one chamber away ? and not some teleport as I used to ? That question of his made me doubt like crazy, as if I always had played that tile wrong.
I may get an answer here....... in ages, but anyway
